After one and half years of experience on the platform of Fiverr, I have learned that when a buyer is reading the gig description then actually he is finding the answers that have arisen in his mind & he wants answers to them. Rather than explaining him that you are the best because your turn around is one or two days, or your experience is blah blah years explain what questions can be arisen after watching the gig. For this, you have to visit your gig as a buyer so you find out what to answer. I find it more attractive rather than an essay looking description.
I have adjusted my gig description in this way. I have linked my description to FAQ also very beautifully.
